How to Use /etc/rc.local?

[tokyo-joe]

I want to configure my display gamma at every boot, so I added the following line in /etc/rc.local.

xgamma -gamma 0.6

However, it doesn't work. When I manually execule the above command from CLI after boot, it works.

How can I make it to perform xgamma command everytime the system boot up?

Will it work if you put the full path to xgamma?

/usr/bin/xgamma -gamma 0.6

And to belabor the obvious, that line is before 'exit'.

You'll need to add this to your bashrc file
When rc.local executes, the graphics subsystem isn't yet loaded

gedit ~/.bashrc

Add at the end

xgamma -gamma 0.6

This method did not work at boot. However, when I start a gnome terminal, it executes "xgamma -gamma 0.6".

hmmm.....

I tried this as you exactly suggest, but it did not work...

I'm unclear as to what xgamma does but if you nee it to be present in your graphical environment then it should go in .xsessionrc in your home directory. The file is not there by default, you have to add it yourself.

I would try 'xgamma -gamma .600' (without quotes) in your Startup Applications.

The file was not there, so I created the file and edited. But it did not work...

Xgamma is a command that adjusts colour setting of your system, by the way. The usage is;
xgamma -gamma [place a preferred gamma value. The default value is 1.0]

Works for me, as this is similar to the gamma setting I use, as it would drop out on reboot with my ATI/AMD 6970 card. Perhaps mention what graphics card you are using.
